Eyebright

Eyebright suppliers and sourcing guide

Eyebright is the dried flowering herb of Euphrasia officinalis and related species such as Euphrasia rostkoviana, small semi-parasitic annuals of European and Asian meadows. Nearly all supply is wild-collected because the plants grow attached to grass roots and are hard to cultivate. Brands buy cut and sifted herb, powder and hydroalcoholic extracts.

Storage, lots and expiry

Storage and shelf life

Keep dried herb and powder sealed in lined bags or drums in a cool, dry, dark place; cut herb loses aroma and color with light and air, and powder picks up moisture once opened. Dry extracts are hygroscopic, so reseal opened containers promptly. Shelf life or a retest date comes from the supplier's specification.

Lots and expiry dates

Wild-collected lots vary in species mix, foreign matter and color, so check each lot's identity and foreign matter results against your specification. Record the supplier lot, collection region and certification, and rotate stock first-expiry-first-out.
